Description

Technical Field

[0001] This utility model relates to the field of electrical connection technology, and in particular to an electrode connection post for a battery and a battery. Background Technology

[0002] In the field of electrical connections, a reliable connection between the battery and the power cord is fundamental and crucial for ensuring the stable operation of various electrical devices. Currently, the industry mostly uses traditional bolt crimping for the fixed connection between the power cord terminals and the battery terminals. This connection structure relies on the tightening force of the bolts to press the power cord terminals onto the smooth contact surface of the connecting post. Its structure is simple and low-cost, hence its widespread use. However, this traditional structure has significant reliability defects in actual long-term use.

[0003] Because batteries are often used in environments with continuous mechanical vibration, such as mobile devices, and due to the cyclic stress caused by the difference in thermal expansion and contraction coefficients of different metal materials at the connection point under current load, the crimping bolts are prone to creep and loosening under long-term dynamic conditions. This loosening not only leads to a continuous decrease in the contact pressure between the power cord terminals and the connecting posts, but also causes poor electrical contact, resulting in power connection failure, power outages, and other usage problems, affecting the user experience.

[0004] Therefore, there is an urgent need for a new type of electrode connection post structure that can provide more stable mechanical locking, excellent vibration resistance and long-term contact stability, so as to fundamentally improve the reliability and safety of electrical connections. Utility Model Content

[0005] The purpose of this invention is to provide an electrode connection post and a battery that can enhance the connection strength between the power line terminal and the battery and have strong vibration resistance.

[0006] To achieve the above objectives, this utility model discloses an electrode connection post for fixing a power line to a battery terminal hole. The electrode connection post includes a post body, and the contact surface of the post body for connecting with the power line terminal is provided with an engagement portion for enhancing the connection.

[0007] Optionally, the column includes a screw and a connecting head fixedly connected to the screw, and the meshing portion is provided on the connecting surface of the connecting head and the screw.

[0008] Furthermore, the engagement portion is an annular sawtooth structure arranged circumferentially around the screw. The engagement portion is configured to press the corresponding surface of the power line terminal when an external force presses the power line terminal to the electrode hole, forming a mechanical lock to increase the connection strength of the contact surface between the power line terminal and the electrode hole.

[0009] Optionally, the connecting head is in the shape of a screw head.

[0010] Optionally, the connecting post is cylindrical, and the two opposite sides of the top of the connecting post are recessed inward to form a clamping portion, which is configured to fit into the jaws of the clip-type power cord terminal.

[0011] Furthermore, the top of the connecting post is provided with an access slot, which can be used to connect a conductive screw to the top of the connecting post to connect another set of power lines, thereby expanding the number of power lines connected in parallel to the battery.

[0012] This utility model also provides a battery, which includes a battery housing and electrode connection posts as described above connected to the electrode post holes on the battery housing.

[0013] Optionally, the battery housing includes an upper cover, a lower cover, and a battery pack embedded in the lower cover. The positive and negative terminals of the battery pack are connected to the connecting post through the terminal hole located in the upper cover.

[0014] Compared with existing technologies, the electrode connecting post proposed in this invention enhances the connection strength and vibration resistance between the power cord terminal and the battery by providing an engaging part on the contact surface between the post body and the power cord terminal. Specifically, when the engaging part is pressed against the power cord terminal into the electrode post hole, it effectively bites into the metal of the terminal, thus firmly pressing the power cord terminal into the electrode post hole and forming a reliable mechanical interlock, fundamentally overcoming the loosening problem caused by vibration. This design ensures a durable and stable connection between the power cord and the electrode post hole and high reliability of electrical conduction. The electrode connecting post has a simple structure, is easy to manufacture, and has good versatility and economy. Attached Figure Description

[0022] To explain in detail the technical content, structural features, objectives and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0023] See Figure 1 As shown, this embodiment discloses a battery, which includes a battery housing A and an electrode connection post connected to the electrode post hole 11 on the battery housing A. The battery housing A includes an upper cover 1, a lower cover 2, and a battery pack embedded in the lower cover 2. The positive and negative terminals of the battery pack are connected to the connection post through the electrode post hole 11 located on the upper cover 1.

[0024] Also see Figure 1 , Figure 2 as well as Figure 4 As shown, this embodiment discloses an electrode connection post for a battery to strengthen the connection between the power line terminal B and the terminal hole 11, preventing the power line from slipping off. The battery connection post includes a post body 3, and the contact surface of the post body 3 for connecting with the power line terminal B is provided with an engagement portion 33 for enhancing the connection.

[0025] See Figure 2 and Figure 4 As shown, optionally, the column 3 includes a screw 31 and a connecting head 32 fixedly connected to the screw 31. A meshing portion 33 is provided on the connecting surface between the connecting head 32 and the screw 31. This meshing portion 33 is an annular sawtooth structure arranged circumferentially around the screw 31. The meshing portion 33 is configured to press the corresponding surface of the power line terminal B when an external force presses it into the terminal hole 11, thereby forming a mechanical lock. In a specific embodiment of this utility model, the annular sawtooth structure can be selected from tooth shapes such as fan-shaped teeth or trapezoidal teeth.

[0026] See Figure 2 and Figure 3 As shown, in the first embodiment of the electrode connection post, the connection post head 32 is in the shape of a screw head, the power line terminal B is annular, the screw 31 of the post body 3 passes through the annularity of the power line terminal B, and then fixes the power line terminal B at the electrode post hole 11 to electrically connect with the battery and realize power supply.

[0027] See Figure 4 and Figure 5As shown, in the second embodiment of the electrode connection post, the connection post head 32 is cylindrical, and the two opposite sides of the top of the connection post head 32 are recessed inward to form clamping portions 34. The clamping portions 34 are configured to fit into the jaws of the clip-type power cord terminal B. In this embodiment, for the power cord terminal B, which is a ring-shaped power cord, the fixing method is the same as the connection method of the post head 32, which is screw-head shaped. In addition, another set of power cords with clip-type terminals can be clamped on the top of the connection post head 32.

[0028] Furthermore, see Figures 6 to 7 As shown, in the third embodiment of the electrode connection post, the top of the connection post head 32 is further provided with an access slot 35. The access slot can accommodate a conductive screw C, allowing another set of power lines to be connected to the top of the connection post, thereby expanding the number of power lines connected in parallel to the battery. See also... Figure 5 and Figure 7 The usage status shown Figure 7 The connecting post can be equipped with an additional set of power line terminals B, which are circular power lines. These are pressed onto the top surface of the connecting post 3 via screw C, thus achieving an electrical connection with the battery. The stackable design of the electrode connecting posts increases the number of power line sets that can be connected, adapting to the power supply needs of multiple devices in parallel and providing scalability.

[0029] Compared with existing technologies, this invention, by providing a unique engaging portion 33 on the contact surface, significantly enhances the mechanical locking and electrical conductivity of the connection while ensuring a reliable connection between the power cord and the battery terminal. During the crimping process, the engaging portion 33 effectively engages the surface of the power cord terminal B, forming a vibration-resistant and anti-loosening mechanical interlock, thereby preventing abnormal heating and oxidation caused by poor contact and ensuring a durable and stable connection. Furthermore, the design of the access slot 35 allows a single battery terminal to be extended to connect multiple power cords, greatly improving the flexibility of use and the expandability of the power supply system. At the same time, the overall structure of the electrode connection post is simple and reliable, combining electrical safety and ease of operation.
